I saw this at the London film festival if I am remembering correctly.
BEFORE seeing it: I read Miike now explores "faith in a godless universe and the intensely queer focus on all colours of 'masculinity'". OK I have to see this!!
AFTER seeing it: Good but I like Miike's other films much better (Gozu, Visitor Q). This is not a bad film. It is a bit too indulgent and slow. Visuals are nice. The visible heartbeat, the smile of the warden (too many times repeated though)... And I can't get over how amazingly cool the prisoners' uniforms were!
